There are plenty of possible answers. One of mine favourite is: go to hell.
1 . Mabye he likes you. 2 . He wants you to notice him or 3. He just tells you everything...
because he did something bad
Move along!
It means she doesn't want to be your girlfriend.
Dump him. If he can't be honest with his friends then he won't be honest with you.
He may be trying to find out if he will miss you.
yes
Yes. The question is why?
ask he or she has a girlfriend or boyfriend
You'll have to break up :( But it is the right thing to do.
I must tell him what my feelings on him. But I will not allow him to be part of my life until he become single or they broke up with her girlfriend.
The answer is up to you. If you feel embarassed to be his girlfriend than maybe he isn't right for you. Only do what you think you should do.
